Smart Mouse (歡樂淘氣鼠) is a Mega Drive game published by Ming/Super Chip and possibly developed by Chuanpu.
The game is essentially a clone of Don't Pull by Capcom (originally part of the Three Wonders arcade compilation, also released as a stand-alone mobile game) which was itself a clone/update of Sega's Pengo, although the graphics and characters appear to be original. As in those two games, the player must defeat all the enemies in a single-screen level by pushing blocks to squash them.
